1982 300TD...

the engine is still idling rough under certain conditions. The idle sounds like it is about to die. It kinda just lopes along or pulsates.

I loosened each one of the injector lines and the result was about the same for all, so I don't think it's the result of a single bad of leaking injector. But I could be wrong since I'm new to diesels.

When the car is in neutral or park it idles rough.

When the car is slowing to a stop, foot off the pedal, it idles rough.

When the car is stopped and still in drive, the idle seems to smooth out.

I would expect the total opposite.

I did adjust the idle speed screw a little to raise the idle, maybe 1/8 turn in.

I have not yet messed with the "rack dampning screw? thing at the rear of the IP.
